Narrative:The Caravelle was backtracking runway 29L when the crew were asked to expedite taxiing and clear the runway on the run-up area because of traffic on finals. While initiating a left turn at the end of the runway the right main gear collapsed. The right wing fuel tank ruptured and the escaping fuel ignited while the Caravelle slid for 90m before coming to rest.
Evacuation of the aircraft was carried out through exits on the left side of the aircraft.
Preliminary investigation revealed that the right landing gear collapsed due to structural failure of a fitting (lower 'candelabra'). A rupture of the fuel tank resulted
and the JP 1 fuel escaping from the tank ignited before the aircraft came to a stop. The source of the ignition was not determined.
